Abstract

As a result of the Siroco system (record on computer of the information contained in applications for building permits), it is possible to measure the consumption of space related to urbanisation. Based on examples taken from Provence, one may note the predominant proportion taken up by housing, the primary role of detached housing which uses eight to ten times the space absorbed by collective housing, the decongestion of towns which is proportionately greater as the town is smaller and which may lead to a quadrupling of the area of a town in the post-war period, the requirements od industry which are greater than those of the tertiary sector.
